Description

Technical Field

[0001] The utility model relates to the technical field of tools for shock absorber maintenance, and particularly relates to a manual rubber bushing removal device for maintenance. Background Art

[0002] The rubber bushing is one of the important components of the shock absorber.

[0003] 1. The rubber sleeve of the automotive shock absorber is made of plastic rubber and has the functions of buffering and shock absorption.

[0004] 2. When passing through some speed bumps with a complete pressure apex angle, after the vehicle tire fully lands, the vehicle body is lifted upward, feeling slightly upward, and the comfort is particularly good.

[0005] 3. It can isolate sound, and the tire noise generated by the tire and the ground is also relieved by it. When the tire is jolted, it can reduce the direct impact on the vehicle.

[0006] The function of the shock absorber rubber sleeve is the last shock absorption function after the shock absorber stroke reaches the highest or lowest point.

[0007] During its normal use, the rubber bushing will be damaged due to factors such as the use environment. The common maintenance method is to replace the entire set of shock absorbers. Currently, in the maintenance field, it is very rare to disassemble and assemble the rubber bushing, or special disassembly and assembly equipment is required for the disassembly and assembly maintenance of the rubber bushing, with very large limitations. Content of the Utility Model

[0008] The purpose of the utility model is to provide a manual rubber bushing removal device for maintenance, which has a simple structure, is convenient to use, portable to carry, safe, and not affected by environmental factors, aiming at the defects and deficiencies of the existing technology.

[0009] To achieve the above purpose, the technical solution adopted by the utility model is: a manual rubber bushing removal device for maintenance, and its innovation lies in: it includes an upper top plate and a lower base, four connecting sliding columns are arranged between the upper top plate and the lower base, a movable plate is slidably sleeved on the connecting sliding columns, a jack is arranged on the lower base, the end of the piston rod of the jack is fixedly connected to the bottom of the movable plate, an upper connecting seat is arranged on the lower surface of the upper top plate, an upper pressing head is arranged at the bottom of the upper connecting seat, a lower connecting seat is arranged on the upper surface of the movable plate, a lower positioning seat is arranged at the top of the lower connecting seat, and a shock absorber rubber bushing is placed between the upper pressing head and the lower positioning seat.

[0010] Further, a compression spring is sleeved on the connecting sliding column part between the upper top plate and the movable plate.

[0011] Further, both the upper pressing head and the lower positioning seat are of hollow structures and are matched with the outer shape of the shock absorber rubber bushing.

[0012] After adopting the above structure, the beneficial effects of the present utility model are as follows:

[0013] Through the pressure action of the jack, and in cooperation with the upper pressure head and the lower positioning seat, the present utility model realizes the disassembly and assembly of damaged rubber. The disassembly and assembly process can be better controlled through manual hydraulic control; this structure is small in size, portable, and can be operated outdoors without external oil, electricity, or gas.

[0016] Description of the Reference Numerals:

[0017] 1 upper top plate, 2 lower base, 3 connecting sliding columns, 4 movable plate, 5 jack, 6 upper connecting seat, 7 upper pressure head, 8 lower connecting seat, 9 lower positioning seat, 10 shock absorber rubber bushing, 11 compression spring. Detailed Embodiment

[0018] The present utility model will be further described below with reference to the drawings.

[0019] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0020] Refer to Figure 1-2 , a manual rubber bushing removal device for maintenance, including an upper top plate 1 and a lower base 2. Four connecting sliding columns 3 are arranged between the upper top plate 1 and the lower base 2. A movable plate 4 is slidably sleeved on the connecting sliding columns 3. A jack 5 is arranged on the lower base 2. The end of the piston rod of the jack 5 is fixedly connected to the bottom of the movable plate 4. An upper connecting seat 6 is arranged on the lower surface of the upper top plate 1. An upper pressure head 7 is arranged at the bottom of the upper connecting seat 6. A lower connecting seat 8 is arranged on the upper surface of the movable plate 4. A lower positioning seat 9 is arranged at the top of the lower connecting seat 8. A shock absorber rubber bushing 10 is placed between the upper pressure head 7 and the lower positioning seat 9. Specifically, place the shock absorber rubber bushing 10 on the lower positioning seat 9, and then start the jack 5, so that the movable plate 4 drives the shock absorber rubber bushing 10 to move upward. The lower positioning seat 9 and the upper pressure head 7 act on each other to press out the shock absorber rubber bushing 10 to be replaced. At this time, the bushing can be withdrawn. After withdrawal, the jack 5 resets, and the upper pressure head 7 and the lower positioning seat 9 are separated; since the jack 5 is controlled by manual hydraulic pressure, the disassembly and assembly process can be better controlled.

[0021] In this embodiment, a compression spring 11 is sleeved on the connecting slide column between the upper top plate 1 and the movable plate 4. On the one hand, the compression spring 11 rebounds to push open the movable plate 4. On the other hand, it can relieve part of the pressure when the upper pressure head 7 and the lower positioning seat 9 act on each other, avoiding excessive pressure and causing damage.

[0022] In this embodiment, both the upper pressure head 7 and the lower positioning seat 9 have a hollow structure inside and are matched with the outer shape of the shock absorber rubber bushing 10, which is conducive to pressing out the shock absorber rubber bushing 10.

[0023] As described above, it is only used to illustrate the technical solution of the present invention rather than to limit it. Other modifications or equivalent replacements made by those of ordinary skill in the art to the technical solution of the present invention shall be covered within the scope of the claims of the present invention as long as they do not depart from the spirit and scope of the technical solution of the present invention.
